In some cases, power systems for example power supply circuit 108 and/or electric vehicle batteries must remain electrically isolated from communication, control, and/or sensor signals. As used in this disclosure, “isolation” is a state where substantially no communication of a certain type is possible between to components, for example electrical isolation refers to elements which are not in electrical communication. Often signal carrying conductors and components (e.g., sensors) may need to be in relatively close proximity with power systems and/or power carrying conductors. For instance, battery sensors which sense characteristics of batteries, for example batteries within an electric vehicle, are often by virtue of their function placed in close proximity with a battery. A battery sensor that measures battery charge and communicates a signal associated with battery charge back to connector 104 is at risk of becoming unisolated from the battery. In some cases, an isolation monitoring signal will indicate isolation of one or more components. In some cases, an isolation monitoring signal may be generated by an isolation monitoring sensor. Isolation monitoring sensor may include any sensor described in this disclosure, such as without limitation a multi-meter, an impedance meter, and/or a continuity meter.

In some cases, power line communication may operate by adding a modulated carrier signal (e.g., communication signal) to a power conductor 112. Different types of power-line communications use different frequency bands. In some case, alternating current may have a frequency of about 50 or about 60 Hz. In some cases, power conductor 112 may be shielded in order to prevent emissions of power line communication modulation frequencies. Alternatively or additionally, power line communication modulation frequency may be within a range unregulated by radio regulators, for example below about 500 KHz.

Still referring to FIG. 1 , in some embodiments, a housing of connector 104 may be configured to mate with a test port. For example, a test port may be identical to electric vehicle port 120. As used in this disclosure, a “test port” is port located outside of an electric vehicle that mates with connector. In some cases, a test port may close a circuit with one or more conductors within connector 104 and thereby allow for said one more conductors to be tested, for example for continuity, impedance, resistance, and the like. In some cases, a test port may be configured to test functionality of one or more of at least a direct current conductor, at least an alternating current conductor, at least a control signal conductor, at least a ground conductor, and at least a proximity conductor. A test port may facilitate one or more signals, for example feedback signals, to be communicated with connector 104 as a function of coupling mechanism 116 being attached with the test port. In some cases, a test port may allow for verification that performance of system 100 is within specified limits.

For example, in some cases, charging performance metrics, may be required to function according to prescribed constraints or specification. Ensuring that charging performance metrics are in compliance with acceptance criteria may, in some cases, constitute verification. In some cases, verification may include ensuring that data (e.g., performance metric data) is complete, for example that all required data types, are present, readable, uncorrupted, and/or otherwise useful for connector 104. In some cases, some or all verification processes may be performed by connector 104. In some cases, at least a machine-learning process, for example a machine-learning model, may be used to verify. Connector 104 may use any machine-learning process described in this disclosure for this or any other function. In some embodiments, at least one of validation and/or verification includes without limitation one or more of supervisory validation, machine-learning processes, graph-based validation, geometry-based validation, and rules-based validation.

Similarly, in a data entry including some textual data, a person's name may be identified by reference to a list, dictionary, or other compendium of terms, permitting ad-hoc categorization by machine-learning algorithms, and/or automated association of data in the data entry with descriptors or into a given format. The ability to categorize data entries automatedly may enable the same training data 1004 to be made applicable for two or more distinct machine-learning algorithms as described in further detail below. Training data 1004 used by machine-learning module 1000 may correlate any input data as described in this disclosure to any output data as described in this disclosure.

For instance, and without limitation, a linear regression model, generated using a linear regression algorithm, may compute a linear combination of input data using coefficients derived during machine-learning processes to calculate an output datum. As a further non-limiting example, a machine-learning model 1024 may be generated by creating an artificial neural network, such as a convolutional neural network comprising an input layer of nodes, one or more intermediate layers, and an output layer of nodes.

For instance, a supervised learning algorithm may include flight elements and/or pilot signals as described above as inputs, autonomous functions as outputs, and a scoring function representing a desired form of relationship to be detected between inputs and outputs; scoring function may, for instance, seek to maximize the probability that a given input and/or combination of elements inputs is associated with a given output to minimize the probability that a given input is not associated with a given output. Scoring function may be expressed as a risk function representing an “expected loss” of an algorithm relating inputs to outputs, where loss is computed as an error function representing a degree to which a prediction generated by the relation is incorrect when compared to a given input-output pair provided in training data 1004.
